In linear algebra, Cramer's rule is an explicit formula for the solution of a system of linear equations with as many equations as unknowns, valid whenever the system has a unique solution.
In math, the purpose of Cramer's rule is to be able to find the solution of a system of linear equations by using determinants and matrices. Cramer's rule makes it easy to find a system of equations that have many unknown variables.
Yes, you can.
Cramer's rule is applied to obtain the solution when a system of n linear equations in n variables has a unique solution.
I suppose Cramer was looking for a generalized method to solve linear systems of equations. Using determinant's was his solution. I've posted a link to a neat site about Cramer's rule.
The history of linear algebra begins with Leibniz in 1693 who studied determinants. In 1750, Cramer invented a rule (Cramer's rule) for solving linear systems.
Cramer's Rule is a method for using Matrix manipulation to find solutions to sets of Linear equations.
Cramer's rule makes it possible to evaluate a determinant without getting confused and making mistakes.
